To all 2li/0m it may concern:

Be it known that l, 'WILLIAM W. WIL- LIAMS, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented a new and useful Reserve Attachment forFuel-Tanks, of which the following is a specification.

It frequently happens that the fuel supply of automobiles becomesexhausted at places where more fuel cannot be obtained or is obtainableonly with great difficulty.

lt is they object ofmy invention to prevent this, at least unless thereis on the part of the driver. In attainingthis object I provide a fueltank lwherein tne fuel can normally be drawn from the tank only to alevel above the bottom thereof,

thus providing a reserve; and means whereby this reserve can be madeobtainable, said means when rendering the reserve obtainable being movedto an abnormal position requiring its return to normal position in orderto refill the tank. Thus the reservecontrolling means is almostinevitably `in position to hold the reserve fuel whenl the tank is full.l o

rlheaccompanying drawing illustrates my invention.

Figure 1 is a vertical central section through an automobile tankequipped withv my invention, the parts being in position to render thereserve fuel obtainable; Fig. 2 is a fragmentary view somewhat similarto Fig. 1, but showing the parts in position to hold the reserve fuel.;Fig. 3 is a partial plan view of the tank with the fillingcap removed;and Fig. l is a fragmentary view showing a modification. y

The fuel tank 10 is provided at the top with a filling neck 11 having ascrew cap 12, and at the bottom with a discharge outlet 13 provided witha stop cock 141, said discharge outlet 13 being connected to anysuitable device requiring fuel from the tank 10., as for instance thecarbureter and engine of an automobile. However, the outlet 13 ldoes notopen directly into the bottom of the tank 10, but at its inner end isprovided with an upwardly extending tube 15` through which its supplymust come. This tube extends upwardly into the tank as far as desired,and is provided with an opening 16 near the bottom of the tank and anopening 17 sufciently above such bottom so that the o ln the arrangementVby the upper amount of fuel contained in the tank below such opening 17is suiiicient for emergenc psc, as to enable the automobile to be drivenor fuel may be secured. Closely fitting around the tube 15is a secondtube 20, which is movable vertically along the tube 15 either to theposition shown in Fig. 1 or to the position shown in Fig. 2. `When inthe lattery position, the tube 20 covers the opening 16, but an opening21 in the tube 2O registers with `the opening 17 in the tube 15 so thatfuel can be drawn from the tank through the discharge outlet 13 by wayof the openings 21 and 17 so long as lthe level of the fuel within thetank does not fall below the level of the opening 17. However, if thefuel level falls below thatpoint, the supply for the outlet 13 is cutoff, although there is still a supply of fuel remaining in the tank. Ifnow the-tube 2() is slid 4upwardly from the several miles or to a placewhere more position shown in Fig. 2 to the position shown in Fig. l, theopening 16' is uncov- `ered and the reserve fuel rendered obtainable.

retaining the tube 2() in its upper position.

means is a spring 25 carried by the tube 2O and having an inturned andupwardly inclined lower end 26, which extends through an opening 27 inthe tube 20. lWhen the ube 20 is drawn upwardly, the latch formed Yopening 17 and holds the tube 2() against being jarred from its upperposition. However, if the tube 2O is pushed downwardly, the inclinedlower face of the end 26 causes thelatter to be pushed outwardly fromthe opening 17 by its cam action on the lower edge of said opening. Theend 26 may also be withdrawn from the opening 17 by t-he operation of abell-crank lever 28 pivoted on a bracket 29 carried by the tube 20, saidbell-.crank lever having one end cooperating with the spring 25 to pushit outward and the other being connected to a cord 30 which extendsupward through a frame 31, carried end of the tube 20, the upper 'end ofthe cord having a knobr32 whereby it may be pulled when desired.Ordinarily it is not necessary to pull the cord 30 with the arrangementshown on Fig. 1, but this cord or its equivalent is necessary if insteadshown this retaining Any suitable means may be provided for y theinturned end 26 springs through the 25 inclined upwardly such end ismade square,.as.is the end 26 inthe modicatien shown in Fig. 4;. `Theupper end of the tube 20 extends into the filling neck 11 when the tube20 is raised, therebypreventing the 'in-i sertion of a funnel into suchneck for filling the tank. Upon fan attempt to insertsuch,

a funnel, the lower end of the funnel presses downward on the frame 31and the tube 20] 'and forces the tube to its lower position,
